【発明の詳細な説明】 （産業上の利用分野） この発明は高濃度コーヒー液と噴射剤とを収納したコ
ーヒー缶詰に関し、特にその噴射剤の構成に関する。Description: TECHNICAL FIELD The present invention relates to a canned coffee containing a high-concentration coffee liquid and a propellant, and more particularly to a configuration of the propellant.
（従来の技術） 上記コーヒー缶詰の噴射剤としては、従来、コーヒー
液の酸化変質を防止することを兼ねて不活性ガスである
炭酸ガスが使用されている。(Prior Art) As the propellant for canned coffee, conventionally, carbon dioxide gas, which is an inert gas, is used, which also serves to prevent oxidative deterioration of the coffee liquid.

As disclosed in Japanese Unexamined Patent Publication (Kokai) No. 1-96886 and Japanese Unexamined Utility Model Publication No. 1-96886, in high-concentration coffee cans, carbon dioxide having high solubility in the contents is used so that the coffee liquid is foamed and ejected from the cans. I have.
（発明が解決しようとする問題点） この従来の炭酸ガスを使用した高濃度コーヒー缶詰か
ら噴射して適切な濃度に薄めたコーヒー液は、独自の風

ある。The following is informed from Table 1. That is, in the high-concentration coffee can of the present invention in which carbon dioxide gas and nitrogen gas are shared as a propellant, the flavor of the injected coffee liquid is not limited to that containing only carbon dioxide gas (Comparative Example 2), but also when shared with nitrogen gas. However, it is better than the one out of the conditions of the present invention (Comparative Example 1), and has substantially the same flavor as the undiluted coffee solution, and at the same time, more canned than using a nitrogen gas-only propellant (Comparative Example 3). That is, scattering at the time of injection is small.
